There's been lots of changes to the software over the last couple of weeks. The biggest being that users with permission to add new users now have full control over the settings for their group. For me this is a bit of a "handing over the keys" moment. Until recently group customisations could only be done using the admin account, but the Site Editor is now available to other users. All the config options in the Site Editor are now listed on the templates page.

The groups permission settings also received an overhaul. From your one initial account you can now set permissions on all the new accounts you create, giving them fine grained access to just the pages they need, or give them full control just like your own account. The settings page under documentaion goes into more detail on how to use the new functionality.
